Calculate the current in amps by dividing power in watts by the voltage in volts.
Current rating of solar panel.
Solar panel efficiency ratings are another important indicator of a modules overall quality and capabilities.
For example if the solar panel is rated at 175 watts and the maximum power voltage vmp is given as 23 6 volts.
Average efficiency ratings range between 15 to 20 percent with the manufacturers lg solar panasonic and solaria currently holding the highest efficiency ratings of the panels currently available although canadian solar rec and solarworld are still comparable in quality.
As we already mentioned all the panels above are composed of 60 solar cells.
A higher efficiency rating is better because it means that your solar panel is able to convert more of the sunlight it captures into electricity.
